Son of Super Chart!

The only good bug is a DEAD bug!

(Guest Post by Matthew Ladner)

Readers will recall Super Chart! showing that teacher quality makes a huge difference in student outcomes, while certification status does not. Drawn from the same Brookings study comes Son of Super Chart, showing that you can pretty much tell who your bad teachers are after a couple of years based on student learning gains.

This isn’t rocket science: invite ineffective teachers to do something else with their professional careers other than damaging the prospects of children. Give highly effective teachers more students and more money.

Now that we’ve sorted out this whole education crisis thing, I’ll look forward to reading Jay’s take on the season premiere of Lost.


The Teacher Glut

June 4, 2008

(Guest post by Greg Forster)

Many of you will be familiar with Mike Antonucci, who is probably America’s last remaining full-time education labor reporter. On his website, he regularly compiles up-to-date Census data on enrollment, staffing, spending and teacher salaries for all school districts in each of the 50 states; he now has almost all the states done for 2005-06.

Lately he’s been commenting on how teacher hiring continues to far outpace enrollment growth; even states where enrollment is flat or shrinking are still hiring like crazy. Maryland, for example, expanded its teacher workforce 10 percent from 2001 to 2006, while enrollment grew less than 1 percent. California, which is still carrying around an extremely bloated teacher workforce from its apparently failed experiment in class size reduction, has just announced that it’s cancelling the large majority of its planned teacher layoffs.

This isn’t a new phenomenon; as somebody pointed out you-know-where, the teacher workforce has been expanding relative to the student population for decades.

What effects does this have? You might expect it to reduce class sizes. The benefits of class size reduction are seriously doubtful and can’t possibly be cost-effective anyway, but never mind that for now. The fact is, class sizes don’t seem to have been reduced. Data from the U.S. Dept. of Education’s Digest of Education Statistics indicate that while the system’s student/teacher ratio has been falling, class sizes have been flat, partly because each teacher teaches for fewer hours per day; there are also probably more teachers with non-teaching assignments (as mentor teachers, etc.) but I don’t know if we have data for that.

One effect the teacher glut is almost certainly to exert negative pressure on teacher salaries. Now, despite what you’ve been told, teachers are not underpaid. (See also the chapter on this in . . . well, you know.) But teacher salaries have remained stable, growing only a little faster than inflation. If we didn’t have a teacher glut, the laws of economics tell us salaries would be growing faster.

So who benefits? Well, the teachers’ unions make out like bandits. More teachers means bigger budgets without the hassle of selling the membership on dues hikes, and more political clout because the public school gravy train is larger. And while the unions’ political clout is badly overestimated – witness, for example, the startling political success of school choice – they do have enough power to exercise significant influence when no one else is looking, such as where staffing policies are concerned.

All of which reminds me of a story Antonucci covered recently (see Item 5 here) about a complaint filed with the IRS by the Ohio teachers’ union against White Hat Management, a charter school operator. The Cincinnati Enquirer reported: “Susan Taylor, president of the Ohio Federation of Teachers, said White Hat, which is supposedly hired by the schools’ boards, exercises too much control over the schools, boards, and finances, violating IRS rules, she said.”

The teacher’s union files an IRS complaint because a tax-exempt organization has too much influence over education policy. So when does the union disband?
